      The rise of China and India is the crucial issue in the Asia-Pacific region. Is peaceful rise of China and India possible? How would other Asian states cope with this new situation? This study has challenged to analyze this by bridging the fields of International Politics, Comparative Politics and Asian Studies.
      Two international symposiums were held: “Emerging New Asian Order? China’s Rise and Power Shift in the Asia-Pacific Region”(June 2015, ICAS9, Australia) and “Globalization and Civil Society in East Asia” (March 2017, Rikkyo U). Based on the latter, a new book will be edited and published in 2018.
